I’m not denying the existence of the phenomenon, how interesting it can be, or even its usefulness in spheres such as medicine. What is bad is when people start charging money for products that offer nothing except abstract placebo and weaving wild fanciful tales of how they’re superior in concrete ways. Then you’ve moved from taking advantage of a psychological predisposition for therapeutic purposes, to exploiting people’s lack of knowledge to hawk products that are usually highly overpriced whilst also spreading ignorance and even mistrust of objective methods. The two aren’t comparable.

I agree. It's bad when people take advantage of other people by using it. More understanding and acceptance of the phenomenon would help those being swindled. I've heard so many times the phrases "it can't be placebo cause I know about placebo!", or "...cause I was expecting the opposite!" which are missing the point completely.

Well, I thought there could be moisture , dust or whatever on drivers , that would dissipate quickly after first use.I got a particular experience with my old iems, the senn ie7 : I found them very bad out of the box, but this impression was gone less than a half hour after.It's commonly believed at head-fi that the senn iems , needs lot of burning .

One would never be done if one took advice from what's "commonly believed" at head-fi. (Full disclosure: when I was a newbie here I also had the same burn-in questions, misinformation spread by head-fiers.)

I don't see how sharing religion from another forum that is in clear opposition to this forum's principles is in any way constructive. Check the unsubstantiated beliefs at the door; they aren't welcome here. Extrabigmehdi, you've been here long enough to know better than to offer a logical fallacy of appealing to popularity, especially after there was a good-faith attempt to further the discussion through scientific experimentation.

And more than likely why you thought them bad out of the box. You've read the previous posts on placebo right?

Placebo, would be indeed the most trivial explanation. But it must be the strongest placebo I've ever experienced . I went from a reaction of disgust, to an opposite one.Unless there's a way for me, to confirm it was placebo; I won't reject any other explanation.

I thought that the popularity of the phenomenon, makes it at least worth a discussion. Sorry, if that's not the case.

My Senn HD555 was perfect out of the box and remained that way until now. Of course I don't have perfect memory of those first days, so it's hard to say if the phones have significantly degraded in those ~10 years of loving service.
